avanturin [10]

Answer: Correct Answer is 4th option , 28


Step-by-step explanation:


We can find the measure of the angle using the tangent.


We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.


So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07


So, angle T rounded to nearest degree = 28


Hope this helps.


Thank you.

At a large company banquet for several thousand employees and their families, many of the attendees became ill the next day. The
yan [13]

Answer:

a. Yes.  This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.

b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error.   A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected.  While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.

Step-by-step explanation:

Total number of attendees who ordered fish = 1,000

Sample size of the attendees who ate fish = 80

Number of attendees who ate the fish and got sick = 64 (80% or 64/80)

Sample size of attendees who did not eat fish = 60

Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)

If you multiply a number by 3 and then add 40, the result is the same as if you add 17 to the number and then multiply by 2. Wha
Finger [1]

Answer:

The number is -6

The second operation is -60

Step-by-step explanation:

Let the number be x.

Solving (a): The value of x

Operations 1:

Multiply by 3: 3x

Add 40: 3x + 40

Operations 2:

Add 17: x + 17

Multiply by 2: (x + 17) * 2

To find x, equate both operations.

3x + 40 =  (x + 17) *2

3x + 40 =  2x + 34

Collect like terms

3x - 2x = 34 - 40

x = -6

Solving (b):

Operations:

Subtract 9: x - 9

Multiply by 4: (x - 9) * 4

This gives:

(x - 9) *  4 = (-6 - 9) * 4

(x - 9) *  4 = -15 * 4

(x - 9) *  4 = -60
